Air con servicing in Sheerwater
Annual servicing and F-Gas leak checks for domestic and commercial air conditioning, for Sheerwater and the surrounding area. Ask us for a fixed-price quote; we reply the same working day.
- Weaker cooling than last year
- Iced-up coils or pipework
- Humming, rattling or squealing from the system
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.
How we handle air conditioning servicing in Sheerwater
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. Each brand sets its own terms, and we can explain what yours says. Our service record shows the work was done. The work covers VRF systems, ceiling cassettes and air-to-air heat pumps, and common reasons people get in touch are an unpleasant odour when the system runs and noisy fans or rattling from the outdoor unit.
Several units at a home near Sheerwater can be serviced in one visit.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Air conditioning servicing in Sheerwater: the local picture
The Valuation Office Agency’s council tax figures date about 41% of homes in Sheerwater and the neighbourhoods around it to the post-war years, 1945 to 1972. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. Roughly a third of a mile or less from central Sheerwater, you reach the Basingstoke Canal Conservation Area. There are 2 conservation areas within a mile of the centre of Sheerwater. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
Site managers at schools like Broadmere Primary Academy can have the site’s units serviced during a holiday. Most homes book one service a year; busy offices and shops may want more.

When it’s something else
Not every problem is solved by air conditioning servicing, and we’d rather say so up front. It will not put right:
- Poor original installation, such as drains without a proper fall
- A refrigerant leak, which needs finding and repairing, not topping up
- A system that is too small for the room it serves
Not sure which it is? You can call us on 07833 053749 or send an email and we’ll tell you honestly before you book.

FAQs for Sheerwater
Do you cover Sheerwater for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Sheerwater is part of that. To start, ring 07833 053749 or drop us a line with a few pictures.
How often should air conditioning in Sheerwater be serviced?
For most homes, once a year. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you provide F-Gas records?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Do you top up refrigerant during a service?
Not as a routine part of the service. If a system has lost refrigerant, it has leaked from somewhere. Where the checks point to a leak, we explain the options for finding and fixing it.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
How long will the engineer be here for the service?
As a guide, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Units that are hard to reach can take longer and we will let you know before the visit.
What we do, step by step
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. In a business, work can often be done one area at a time. The work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Visits to Sheerwater are agreed with you in advance and planned so the job can be finished in one trip where possible.
- First we take the details: brand, model if you have it, how many indoor units and anything that’s been bothering you.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters, coils and the condensate drain are cleaned and cleared.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- You get a service record, with anything that needs attention explained.
Preparing for the visit
- Let us know where the consumer unit is
- Let us know where we can park and unload
- Make sure we can reach the outdoor unit, or where it will go
Ask for a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

Looking after your system
How well a system lasts depends on use and care. Here’s what we suggest:
- Know your manufacturer’s servicing conditions
- Leave space around the outdoor unit for air to flow
- Hold on to every service report
Where the system needs F-gas leak checks, the result is recorded, and the next check is due within the period the rules set. We can diary it for you.
Book a service at least once a year, and more often if the system works hard or the rules require it.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
